Check out the screen shot I provided. RAM is in 2x512 dual channel running at 250MHz and I can't get the value in red set to 1 w/o lock up. Any ideas? Also any other changes to help improve performace would be greatly appreciated!

I'm trying to get a good idea what settings are set to what in a fail safe config. I'm trying to start with the most conservative settings imagineable to try to figure out if I can get this notebook's RAM to do 200Mhz.

Can someone set their mobo's BIOS to fail-safe or something similar and then load up A64Tweaker and share what the settings are?

Sorry guys Ive been out of the overclocking scene for the last month or so to pursue a new hobby ... snake breeding.

The offcial release of A64 Tweaker is V0.31, this is also the best one to use. I did produce V0.5Xt which added some HTT settings, but these dont work. THe latest (untested) release is 0.6 which adds a few minor features such as Drive Strength etc etc.

My new hobby will go quiet around May/June, thats winter over here and its also when snakes are at their quietest. So maybe around that time I will get another A64 rig and start the overclocking again.

I have a dream.....and that is that A64Tweaker can have the snazzy feature of setting a 4x multiplier on my notebook while it is applying its settings. I've found that the only way to guarantee no lock up when changing the RAM clock speed is to literallly unplug the thing from the AC power (or use a proggy to set it to minimal power use, but the ac plug is much less of a pain to do)......

edit:
I managed to figure out a crazy way around this lockup problem. By using a batch file and removing the AMD processor driver (using MS's OEM driver), I disable PowerNow. Instead, using the batch file, I have Clockgen set the FID to 4x, then apply A64Tweaker, then load up RMClock which simulates PowerNow (and does it better with voltage controls and many advanced settings).

Now... Let's get on with it In your latest release - v0.60 - you added quite a few new options like Drive Strength, DQS Strobe Timmings.... By doing so you pretty much gave MSI K8N Neo2 users all the RAM tweaking options that they've never had available in BIOS but e.g. DFI NF3/NF4 enjoyed for some time now . But there's one more I'd like to see - Bank Interleave 2-way/4way

Is it possible to add that option at all ??? Can you comment on that, please...

Best regards,

EDIT: Damn.Silly me. I must have missed Tictac's post above about bank interleave... Hopefully, you will be able to add it in your next revision.

Codered thanks for ur great tool once again
the load profile doesn't work correctly on version 0.5 and 0.6, are you planning on fixing it?
Also the LDT multi on version 0.5 was working fine, imo this is the option that should stay on future releases as it's the only tool that could change it on the fly...

A fix for V0.6 will have to wait until I get another A64 rig .. probably around May/June (thats winter down here) before I start overclocking again.

The LDT multi in 0.5 only appears to work. This version only changes the CPU registers not the chipset and doesnt perform a LDT reset so the changes dont actually take effect. Some of the buffering parameters do however seem to take effect. If I could get hold of the chipset data sheets than maybe this feature could be made to work properly.

V0.31 is still the latest fully tested release. The others were just experimental and couldnt be tested due to my lack of hardware.

As for mem interleave, its very unlikely that this feature will work from within windows. Changing the interlave will also change the physical memory map and thus screw up everything already loaded into RAM. It may be possible to put the machine into a hybernation mode, page everything to disk, change the interlave and then reload the mem image form disk, but unfortunately I dont have enough technical info on how this is done by windows.

I want ecc memory support of the unregistered dimms. The Asus A8n-sli Deluxe (according to bios option and manual) and the DFI nforce4 boards support ecc (according to a review I read). It does not seem from the info I have been able to gather that the shuttle sn25p does support ecc in the bios.

From my reading of an AMD tech document on the socket 939 processor, ecc is a processor thing. So that processor does support ecc of its unregistered DIMMs.

So my question is , if the sn25p does not support ecc in the bios, if I run the A64 Tweaker utility, will it really be able to override the bios and add the ecc functionality to the sn25p? Can someone tell me technically why it should or should not be able to . What could get in the way of that on the motherboard level? Will ecc unregisted dimms work in the sn25p, during the times the A64 Tweaker is not running? In other words , will the motherboard be smart enough to not use the extra ecc chip on the dimm during initial boot up?

Can a64 Tweaker be incorporated into the boot up sequence? After the ec switch is set iin the Tweaker, can you shut down tweaker and the ecc will continue withought having to have Tweaker continue in the background?

Thanks,

Oh, and how can you tell for certain the ecc is really being used, and not just see a Tweaker switch? How does that really work? Can you tell if you run a memory benchmark without ecc, then run the same benchmark with ecc, and there should be a like 1/8th decrease is memory speed or something?

Oh, I take it, that once you shut down the Tweaker program utility, all the settings you made will continue until the computer shuts down?

Will A64 tweaker be able to start up from inside the new 64 bit windows that is being realeased?

If I wanted to run Linux or 64 bit Linux but needed the ecc switched on, could I boot into windows, switch it on though the Tweaker, then boot into Linux without hitting the reset switch. I don't know what I am talking about here. Would there be any sequence that would keep the toggles on the memory?

Is that TCCD stuff you are running? And it works at a cas of 1.5? (A64 tweaker crashes if I even try to change CAS ot a higher value for me and I am using the same board + TCCD, although I am using a winchester...)

why everytime i press the set button on the amd64 tweaker my system reboot or hang?
i've follow the setting on the first post, is there any other steps that i need to do before changing the value using amd64 tweaker
